BOBBIN-WINDING MACHINE.

Application filed May 21, 1926. Serial No. 110,796.

This invention relates to an improved machine forwinding double headbobbins.

One object of the invention is to provide an improved machine whereinthe empty or partly empty bobbins are automatically fed from a hopper orrack to a chuck, or equivalent device7 by which the bobbin is revolvedto wind the yarn thereon, and during the winding there is areciprocating movement between the yarn and bobbin whereby to distributethe yarn over the bobbin. When the yarn is wound to the desireddiameter, automatic means are provided to cut the yarn, discharge thefilled bobbin and feed another empty lor partly empty bobbin to thechuck.

Other objects and advantages, such as discharging a bobbin in case theyarn breaks and supplying a new bobbin, will be pointed out as thedescription proceeds. n

The invention is illustrated in the accompanying drawings, wherein,-

Fig. 1 shows the machine in side elevation.

Fig. 5 shows an enlarged vertical crosssectional detail through themachine,-the section being taken on the line 5-5 of Fig. 2 looking inthe direction of the darts.

Fig. 6 illustrates in a diagrammatic perspective the several cams andthe devices actuated thereby.

Fig. 7 shows two of the winding units in top or plan view.

Fig. 8 lillustrates one of the units in front elevation.

Fig. 9 shows one of the units inv top or plan view with the chuck-partsin the released position to discharge a filled bobbin. and

Fig. 10 illustrates a vertical sectional de-l tail through the yarnvguides to show how the yarn is held as the cutter engages the same tocut it.

Referring to the drawings and particularly Figs. 1 to 1 thereof.v thenumeral 12, designates a hase of any suitable construction, provided. inthis instance and at the rear of the base with a suitable frame 13.which carries a platform 14, on which a series of verticaly spindles aresustained. These spindles form supports for supplies of yarn 16 whichlatter are to be drawn oil' and Wound onto double-head bobbins such asvare employed in various cloth-making machines. v

Above the spindles the frame 13, sustains one or more horizontal shafts,in this instance three in number and designated 17-18 and 19respectively. These' shafts carry a plurality of guides 20 andthejstr'ands of yarn 16 are led from the supplies and passed around thesaid guides on their way toward the bobbins.

At the front of the machine suitable standards 21 are provided whichlatter carry a horizontal rod 22, on which tension disks 23 are properlyspaced whereby each strand is kept under proper tension during thewinding operation.

Cross-bars 24 are also employed in the present instance to connect thefront standards 21 with the rearframe 13 whereby to produce rigidity inthe structure, and suitable brace bars, such as that shownat 25, servethe same purpose.

In the design and operation of my improved machine, I have elected tocentrally locate the driving and main actuating elements and to provideindividual winding-units at opposite sides of the central drivingelements so that a plurality of units may be operated from a singledriving mechanism. i

The number of winding units at each side of the single driving mechanismmay vary, but in the present disclosure of my invention. I show twounits at oneside of the central mechanism, presuming that the samenumber are arranged at the opposite side, but this is for illustrativepurposes only in this particular instance. 4

On top of the base 12, and at the front corners I provide verticalbearing frames 26 and between said frames, I also mount on the base acentral frame or housing structure which includes two spaced-apartvertical bearing plates 27. The bearing frames 26 and the plates 27 forma supporting structure for certain shafts, bars and rodsthat extendhoriontally but in an elevated position above the ase.

A stationary flat bar 28 extends horizontally across and is secured atthe front edge of the supporting structure and this flat bar, inaddition to other uses. serves to tie the several vertical bearingframes and plates together.

The bearing-plates 27 are, in this instance,

lli)

spaced'suiciently to form a housing or frame like v'structure for themain 'driving mechanisms from which the various parts of the machine areactuated.

These driving mechanisms include a horizontal shaft 29, on which a main'pulley 30 is mounted,-the pulley being driven by a belt 31 that passesabout the pulley of a motor 32. f course, any suitable driving means forshaft 29 may be employed. At the side of the pulley 36, I provide apinion 33, which is driven as 'the shaft 29 is revolved, andv thispinion meshes with and drives a gear 34 on a short horizontal shaft 35.

\ The gear 34 meshes with and drives a gearf 36, on a worm-shaft 38,said latter shaft carrying' aworm 39 that drives a worm-gear 40. Thisworm-gear 40 is carried on shaft 41 which extends in a direction'foreand aft of the machine or at right angles t'o the shaft 29. This shaft41 may be termed a cam-'shaft because it carries a series of cams whichwill presently be described, and the cams. on this cam-shaft areconstantly revolved.

At each end of the machine, I provide the vertical bearing frame 26 witha rearwardly* extending arm 42, (see Fig. 7) through which a horizontalsupporting and tie-rod 43, extends from one end to the other of themachine. This tie-rod 43, also passes through the verticalbearing-plates 27, which give it additional support between its ends.

Another tie-rod 44, extends horizontally from end-to-end of the machineand is also supported by the vertical bearings 26 and 27. Both of thetie-rods 43 and 44 are stationary and have no movement.

The bearing 26 and the bearing-plates 27 are each provided with abearing-head 45 in which a chuck-head or a head-stock 46 ismounted,-each head-stock being provided with a pulley 47, for the travelof abelt 48, that extends downwardly and passes around aI pulley 49, onthe horizontal pulley-shaft 29.

As the mechanisms coacting with each head-stock 46 are identical andthere are a plurality of such stocks employed in the machine disclosed,a description of one will apply with equal effect to the others.

A tail-stock 50 coacts with each head-stock and each tail-stock iscarried on a bracket 51. This bracket 51, has a rear bearing 52 that isloosely sustained on the tie-rod 44, and is provided with a 'forwardbearing 53 that loosely engages a horizontal reciprocating rod 54, whichextends throughout the width of the machine.

It is yto be understood that the rear rod 44 is simply a'support onwhich the bracket 51 sli des, whereas the rod 54 is a continuouslyreciprocating rod and will reciprocate through the front bearing of thebracket when the latter is in the operating position with respect to thehead-stock. which is during the winding operation. The reciprocatingmovement however of this shaft 54 is utilized to restore the tail-stockto its normal winding position after it has been shifted to one side torelease a filled bobbin and allow an empty bobbin to be supplied, aswill presently be more fully eX- plained.

Each tail-stock bracket 51 is provided with an arm 55 which extendshorizontally in front of the tail-stock and toward the head-stock 46 andthis arm carries a cutter blade 56 for a purpose that will alsopresently be explained` It is thus to be understood that any horizontalmovement imparted to the tail-stock and its bracketl will also beimparted to the arm 55 and cutter blade 56.

Beneath the .cutter-blade arm 55 there is lprovided ahorizontally-extending trip-lever 57, which latter is pivoted at 58, tothe upper side of the stationary bar 28. This lever will therefore swingin a horizontal plane.

One end of this lever 57 has a coiled spring 59 attached thereto so asto normally keep Y said end drawn toward the space between the twochucks or'h'ead and tail stocks.

The opposite end of this trip-lever 57 has a tapered edge 60 at itsinner side while its outer side has a straight edge 61, which is insubstantial vertical alinement with the vertical edge of the stationarybar 28 and both of these edges perform' useful functions as willpresently be explained.

Beneath the trip-lever 57 there is provided a pivoted trip-dog 62 whichlatter has a pointed trip-end 63, at one side of its pivot 64 and isalso prvdedwith a hook 65 at the opposite side of said pivot.

`At the latter hook-end the dog also carries a pin 66 and a coiledspring 67 isattached to .this pin and constantly draws the hook endinwardly and tends to project the trip-end 63 outwardly.

A trip-linger 68'is carried at one end of the trip-lever 57 and thisnger (see Fig. 7) normally has position between the two chucks 46 and50. The position of this trip-finger 68 is such that if it be pressedforwardly it will swing one end of the trip-lever forward projectsaround and engages the side edge of the chuck bracket 51 and holds thetail-stock 50 of the chuck in the operating position. This is alsodiagrammatically illustrated in Fig. 6 of the drawings.

The forward bearing 53 of the tail-Stock 50. as has been stated, isslidably sustainediau on the reciprocating rod 54 and a spring 69 iscoiled on said rod and is compressed between the movablebearing 53, andthe stationary bearing 26 or 27 as the case may be. i

By this means the spring 69 constantly tends to push the movabletail-stock bearing on the rod 54 in a direction that would separate thetail-stock from the head stock, but the hook 651 on pivoted dog 62,normally holds the tail-stock against this lateral displacement.

The trip-lever 5 7 and its trip-finger 68 normally, during the windingoperation, have the positions shown in the top view in'Fig. 7 and thetrip-dog 62 with its hook 65 holds the tail-stock against the action ofthe spring 69. This condition prevails until the tripiinger 68, ispushed outwardly by the wound yarn on the bobbin, at which moment it isdesired to release the tail-stock 50 and allow it to move laterally soas toreleasefthe filled bobbin. This release operation of the tailstockis effected bythe withdrawal of the hook on the trip-dog and themovement of the dog is caused by means which will now be explained,reference being made particularly to Figs. 2-78 and 9 of the drawings. l

To the horizontal bar 28 I attach a plurality of bearing brackets 70,and these brackets carry arcciprocating rod 71 that extends horizontallythroughout the width of the machine.` The means for reciprocating thisrod- 71 will presently be explained.,

The rod 71 extends horizontally across the front of the machine and pastthe several winding units,'and at leach winding unit I provide aclamp-bracket 72, on the rod. Each clamp-bracket is provided with a pawl73, whose upper end is pivoted to the bracket and whose lower end 74hangs pendantly and normally slides on top of the straight-edge side 61of thetrip-lever 57, as it is carried back and forth in a horizontaldirection with the reciprocating rod 71. As long as the lever 57 is inthe normal position so the lower end of the pawl can slide thereon, thelatter will simply slide over said edge 61 and ride over the trip-end 63of the dog. When, however, the lever 57 is tripped and moved to theposition shown in Figs. 8 and 9 of the drawing, the lower end 74 of thepawl will drop down upon the top surface of the bar 28 because Athelever 57 has been swung laterally from beneath the pawl.

When the pawl-end 74 drops down onto the bar 28, and it makes its nextmovement with clamp 72 toward the head-stock 46, it, the pawl, willengage the trip-end 63 of the dog 62, and push said dog-end inwardlyover the bar 28, thereby swinging the hook-end 65, from engagement withthe tail-stock and thus release the latter so the spring 69, can throwthe tail-stock laterally until the bearing 53 of said tail-stock strikesthe stationary collar 75 that isl fixed on the reciprocating rod A54, asclearly shown in Figs. 8 and 9 of the drawings. Y

When the tail-stock ,50 has been moved laterally, it carries the arm 55with it because the latter is attached thereto and as the cutter-blade56 is carried by said arm, this blade will also be given a suddenlateral movement in order that it may sever the yyarn and entirely freethe bobbin. f

Each winding unit is provided with a hopper in which a series of emptybobbins are stored so that when one bobbin has been revolved in thechuck, and the required quantity of yarn wound thereon, it will bereleased through the action of the trip-lever,

ldog and movable tail-stock and discharged ,in broken lines in Fig. 3 ofthe drawings.

These concave ends 81 vof the lifter-arms are voff-set or extendforwardly fromthe curved rear faces 83 of said arms, and by reference tosaid Fig. 3 it will be seen that said ends are so off-set thatvthe forthe lowermost bo bin while the curved rear-faces 83 of the arms extendthrough an arch which, if extended, would pass between said lowermostbobbin and the empty bobbin next above it. The reason for this is thatas the arms are swung up, as will presently be explained,.to lift thelowermost bob- `bin from the chute up to a position to be engaged by thechucks, the curved faces 83, of the arms will engage the second bobbinand prevent it, and the bobbins in the chute above it, from droppingdown until the arms 80 have again been lowered.

The lifter arms 80 are each carried on an 11p-turned end 84 of a liftinglever 85. These levers 85 have clamps 86- at their ends which will forma support clamps rigidly engage a sleeve 87 that is concave upper ends81 ofy said arms to best deliver the empty or partly empty bobbns intothe chuck.

A spring 91 engages the lower end of each arm 80 and yieldingly drawsthe lower end thereof toward thestop-screw.

By reference to Figs. 3-4 and 6 of the drawings, it will be noted thatone of the levers 85 of each winding unit is provided with a. notch 92in its upper side and that a latch-bar 93, is pivotally attached at itsupper end to a lug 94 that Idepends from the movable tailstock 51 andhas its lower end engaged in said lever-notch 92. A spring 95, engagesthe latch-bar 93 and merely braces the lower end thereof to prevent thesame from swinging loosely.

To each unit, comprising the two lifterlevers 85, there is attached acoiled spring 96 of sufficient strength to lift the levers 85,

v arms 80 and to turn the sleeve 87 on the shaft These 88, during suchlifting operation. levers and arms however are held down against thepull of the spring 96 and in the positions shown in Fig. 3-4 and 6,-bythe latch-bar 93 engaging one of the levers.

On the end of the sleeve 87, I provide a clamp-head 97 (see Figs. 4`6`and 8 of the drawings) and from one side of this head there projects apin 98, that extends horizontally and in a direction parallel with theshaft88. l

At one side of but spaced from the head 97, there is a. collar 99 on theshaft 88, which collar is rigid on the shaft and oscillates as the4shaft 88 is rocked. This collar is provided with a pin 100 whichprojects from one side thereof and in a direction toward theclamping-head 97 and the pin 100 on the collar and the pin 98 on thehead lap.

The positions of these two pins 98 and 100 are the same with respect tothe axis of the shaft 88, but when the levers are in the normal positionand the arms are supporting the row of bobbins 82 as in Fig. 3, thesepins are separated suiciently to permit the shaft 88, collar 99 and itspin 100, to oscillate or rock without the pin 100 engaging the pin 98,but these pins will be brought int-o engage'- ment when the arms 80 havebeen swung up to deliver an empty bobbin to the chuck, so that saidarmswill be returned against the lifting action of the spring 96. This willalso presently be more clearly explained.

It has hereinbefore been stated that shaft 88 continuously rocks backand forth and that rods 54 and 71 continuously reciprocate.

The means for effecting these operations will therefore now beexplained, reference being made particularly to Figs. 2-5 and 6 of thedrawings.

The central horizontal shaft 41 which extends fore and aft of themachine carries a heart-shaped cam 102. At the front of this guide forthe same.

The bar 1'04 carries two rollers 106 and 107 which are locatedat'opposite sides of the cam 102 so thatas the cam revolves first oneroller and then the other will be engaged and the bar 104 thereby beconstantly reciprocated.

In front of the bars 104 and 105 there is provided a vertical slottedbar 108 whose lower end is mounted on a horizontal pin 109 that hasbearing in a block 110 beneath the worm-shaft 38, as best shown in Fig.5 of the drawings.

Obviously, as the cam 102 reciprocates bar 104, the bar 108 will beswung back and forth.

The upper end of this bar 108 is attached to a block 111 which iscarried on the horizontal rod 71,-the attachment being made by a pin 112extending through the slot of bar 108 and as vertical bar 108 swingsback and forth it imparts a. reciprocating movement to the rod 71, for apurpose that will presently be explained. l

At the rear of the worm gear 40, the central shaft 41 carries apear-shaped cam 113. This cam has position directly beneath the rod 54,and two arms 114'depend from said rod 54 at opposite sides ofthe cam 113so that said cam will engage one of said arms to move rod 54 in onedirection and will then engage the other arm to move the rod in areverse direction.

The rod 54 is therefore reciprocated horizontally and continuously,through the bearing plates 26 and 27, and also through the bracket 51 ofthe tailstock,the latter being held against the expansion of the coiledspring 69 by means of the hook 65, during the winding of the bobbin 82that is held between the head-stock 46 and the tail-stock Behind thepear-shaped cam 113 I provide another cam 115 on the shaft 41. This camrevolves with its periphery in close proximity to a roller 116 that ismounted on an arm 117 whicharm is mounted on and extends rearwardly fromthe shaft 88.

The worm-gear 40, and cams 102-113 and 115 are all secured together bypins 37 (see broken lines in F'ig.l5) which extend horizontallytherethrough, which maintains them in proper operative relation.

During the winding of the yarn on the bobbin it is desirable that theyarn be given a traverse motion between the opposite ends of the bobbinand with this in view I attach to the reciprocating or traverse rod 71 ablock 118,-one of these blocks being provided at` each winding unitimmediately above the bobbin-space between the two chucks. Each block118 carries a yarn-guide 119 having the form of wire arms with a slot'16 should break I provide means whereby the tail-stock 50 will bereleased, the bobbin discharged and a new bobbin immediately fed betweenthe chucks.

The means for effecting this operation will therefore now be explained,reference being made particularly to Figs. 3 6-7-8 and 9 of the drawingsr To t-he side of each traverse block 118 on the rod 71, I pivotallyattacha plate 120 so that -the plate will move with'the block 118 andshaft 71 but may swing in addition to its traverse movement. This plate120 carries a wire trip-arm 121 which extends upwardly and rearwardlyand has a horizontal stretch 122 whichlies against thedownwardly-traveling yarn thread 16, as best seen in Figs. 3 and 6. Thethread of yarn therefore holds the trip-arm 4121 up.

The lower end of the pivoted plate 120, carries a wirel finger 123 whichextends laterally, downwardly and rearwardly therefrom.

From the end of the trip-lever 57, there projects an arm 124 and thisarm turns laterally and has position adjacent to the wire finger 123 ofplate 120.

In case the yarn 16 breaks, the wire triparm 121 will dropdown, as shownin broken lines in Fig., 3 which causes the plate 129 to swing the wirenger 123 forwardly `against the arm 124, and move the latter forwardly.When arm 124 is thus moved forwardly it pulls one end of the trip lever57 forwardly and swings the straight edge side 61 of said leverrearwardly so as to allow the pawl 73 to dro down on bar 28.

'lillen as the pawl 73 makes its forward stroke it engages the trip 63on the dog 62 and withdraws the hook 65 from engagement v with thetail-stock, just as it would do if tripfinger 68 were operated by thefilled bobbin,

and the tail-stock then moves laterally and drops the bobbin frombetween the chucks.

Having described the construction and arrangement of the mechanisms, abrief expla- Having thus connected a strand of yarn 16 `with the severalbobbins, one bobbin at each unit will be automatically placed betweenthe head and tail stocks when the machine is started.

As the bobbin is revolved by the beltdriven pulley 47 on the head-stockthe yarn will be wound thereon,` during which operation the Iyarn guide119 is caused to traverse over the -bobbins and distribute the yarnthereon.

Vhen the yarn on .a bobbin has reached a sufficient diameter, it willpress against they trip 68,- and push the latter forward carrying oneend of lever 57 with it and swinging the opposite end of said leverrearwardly.

During this winding operation the rod 71 is constantly reciprocatingcausing a pawl 73 at each unit to travel back and forth over the edge ofthe lever 57. When this lever is moved however by the yarn on thefilled` bobbin, this pawl 73 will drop down and when it is carried backit will engage the trip-end 63- of the dog and withdraw. the catch orhook 65 from the tail-stock 50, whereupon the coiled spring 69 willthrow the tail stock laterally, release the filled bobbin and at thesame time the cutter 56 will sever the yarn from the releasedtail-stock.

As the tail-stock 50 is released and moved laterally, the latch-bar 93is disengaged from the lifting levers and the latter are drawn up by thespring 96.

These levers carry the lifter arms 8O which raise the lowermost bobbinfrom the chute and lift it to la position between the chucks or head andtail stocks.

When the levers 85 swing up, the sleeve 87 117, the pin on the collarwill engage pin 98 on the Clamp and swing said clamp in a direction thatwill lower the levers 85 and arms 80 to their normal position.

Just before the return movement of the levers 85 and arms 80, shaft 54will be reciprocating in a directionthat will cause the collar 75thereon to engage the movable tailstock and push it back soas to engagethe empty bobbin and when it engages the bobbin the arms 8O return orlower, catch 65 engage the stock and latch-bar 93 will again engage thelevers 85 and hold them down and the operation is 'repeated on the nextbobbin.
